Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The contact owns a 2004 Chevrolet Blazer. When the gear was shifted into reverse, the vehicle would not move. The dealer stated that the failure was caused by a faulty sun gear. The transmission needed to be replaced in order to repair the failure. No repairs were made. The current and failure mileages were 112,000.

Blazer 6-cyl

  • Automatic transmission

Car started making a rattling noise when I turned to the right shortly after having a spring replaced in drivers side front tire. Within a week the rattling progressed to a grinding. Dealership refused to look at it, knowing I was about to go on a long trip. I left for my trip (9 hour drive) after about 5 hours, this grinding noise was constant, then ABS light came on, started messing with my steering, then, while trying to get to a dealership in the closest city ( still an hour away from my destination) tire broke off at the bearings while driving down a major 4 lane highway. Thank goodness the other cars were able to miss me, avoiding a major accident. Although I was told you don't have a lawsuit unless there's an injury, so I don't know if it was good or not!!!!! the transmission would slip when shifting from first to second gear. Updated
